Good day, I am new to the Docker Forum, I am installing Cyphon onto a desktop inside of a enterprise domain. I have followed all the directions listed at Cyphon.io but when I get to Development Environment:
$ cd /opt/cyphon/cyphondock
$ sudo docker-compose -f docker-compose.yml -f docker-compose.dev.yml up
I am prompted for [sudo] password for UserName: After typing in my correct password. The return function is:
“Pulling postgres (mdillon/postgis:9.6)…
ERROR: Get https://registry-1.docker.io/v2/: x509: certificate signed by unknown authority”
I have copied and put my Domain Cert in /home/documents folder and even copied it to the /home/certs folder. I then ran $ sudo cp /home/UserName/certs/xx-xx-xx.crt /usr/share/ca-certificates/extra/xx-xx-xx.crt to install my domain cert. But I am still getting: ERROR: Get https://registry-1.docker.io/v2/: x509: certificate signed by unknown authority.
How does docker view certs, how do I resolve. At a stand still. Thanks
Running Ubuntu 16.04
